LIQUID-FUEL BURNER.

Application flied January 2,

To all whom it may concern Be it known that I, Gnonsr. EDMOND DEN- MAN,a citizen of the United States, and a resident of Fruitvale, in thecounty of Alameda and State of California, have invented a. new andImproved Liquid-Fuel Burner, of which the following is a full, clear,and exact description.

This invention relates to burners through which the liquid fuel isforced out into a fine, evenly subdivided spray, the particles fluid, bymeans of which the atomizing of the liquid fuel is obtained, and hasreter ing an inner and an outer casing having independent inlets, onefor fuel and the other for the compressed fluid, and a tip body securedto both of said casings and through which. the liquid fuel is forced bymeans of the compressed fluid.

The object of the invention is to provide an inexpensive, simple andeflicient burner which can be easily cleaned, repaired and its Wearingparts easily assembled.

' A further object of the invention is to )rovide a burner in whichdifferent tips can be used.

Reference is to be had to the accompanying drawings forming a partofthis specifi cation in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a longitudinal central section of an embodiment of myinvention; Fig. 2 is a horizontal central section through the tip body;Fig. 3 is a modified form of the tip body; Fig. 1 is a perspective viewof the cap; Fig. 5 is a perspective view of the distributing cup partlycut away to show the distributing orifices; Fig. 6 is a perspective viewof the central dividing washer; and Fig. 7 is a perspective viewritlnuunpe a d lower spray-forming cut-away washers.

Referring to the drawings, 10 represents a compressed fluid inlet 12leading to the through bore 11, and a liquid fuel inlet 13 lyingopposite-the fluid inlet 12, both perpendicular'to the bore 11. The fuelinlet 13 leads to a central bore provided with a body portion 14extending from the center of the cross member toward one end of'thesame, and it is concentric with the bore 11. In the end of the bore 11lying opposite the central body portion 14 is a threaded capSpecification of Letters Patent.

at the inner projecting end, provided with a valve head 18 normallyforced against the adjacent end of the bore 15 by means of a coil spring15) positioned on the plunger 17. By pulling on the exteriorlyprojecting end of the plunger 17 the I spring 19 is compressed and thevalve head 18 of the plunger 17 is drawn away from the through bore 15thereby establishing communication between the bore 1.1 and the bore 15.

Connected exteriorly to the cross member 10 by means of a union 20 is anipple 21 axial with the bore 11 and at the end to ward which thecentral body portion 14 extends. A tubular member 22 13 securedcentrally to the body portion 14 axially with thebore 15, and the saidtubular member 22 projects out at the opposite end of the nipple 21.Secured directly to the tubular portion 22 and to the nipple 21 by meansof a union 23 a plug having a central bore 24 and a plurality ofpassages26. A cap 27 is screwed to the other end of the plug 25 and it has a.through bore substantially equal to the end bore of the plug 25.'llhreaded into the central bore 24 of the plug 25 is a tip body 28,having a shoulder 29 abutting snugly 'against the free nonthreaded endof the cap 27. By screwing off the cap 27 from the plug 25, the abuttingjoint between the tip body and the cap is made tight. The tip body 28has a semispherical end portion provided with a slit 30 connected to thecentral passage 31 of the tip by means of a flattened passageway 32converging from the slit toward the bore. The'portion of the tip lyingin rear of the shoulder 29 is conical, and its slope is parallel withthe slope of the passage 32 A pair of apertures 33 is provided in theconeshaped portion of the tip opposite each other and converging towardthe end of the passage 32 and terminating in the flattened Another pairof passages 34 is provided in said cone-shaped portion opposite eachother and at right angles to the passages 33 in the beveled sides-of thepassage 32. As the passages 33 and 34 lie exteriorly on the same circleon the cone-shaped portion of the tip they terminate inwardly atdifierent distances from the end of the tip due to the fact that onepair enters the flattened 'portion of the passage 32 and terminatingwhile ithe other pair said shank communicating With said outlet passageon the shank and having distributing apertures'in the'bottom thereof, aplu-' rality ofWashers between said oupand said central eXtensiph, and athreaded cap on said shank closing said cup and maintaining same on saidWashers in a predetermined position, certain of said Washers below saidcup and above said central extension having.

cut-away portions in alinement with each other and under saiddistributing apertures of said cup.

3; A device "of the class described com: prising, an exterior tubularmember and an interior tubular member; a plug at one end secured to saidexterior and said interior tubular members, said plug having'a centralpassage communicating with said inner tubular member and a plurality ofpassages surrounding said central passage communicating with saidexterior tubular member; a

tip body secured to said plug and having a 'central passagecommunicating With said sage communicating-With said surroundingpassages in said plug, said passages in said tip body having, acommonoutlet at the tip end, said .central passage of said tip having anoutlet above said common outlet; and a' cross member secured to saidexterior and interior members at the end opposite said plug and havingindependent inlets to said exterior and interior tubular members.

In testimony whereof-I have'signed my name to this specification'i'n thepresence of two subscribing Witnesses.
